+ DE-MACRO
+
+Version 1.3 - this version is much more conservative about deleting
+ comments and inserting or deleting blank space: tries to
+ leave in all comments, adds space only when necessary, and
+ tries not to delete space in the main text.
+ The motivating comments came from Daniel Webb.
+Version 1.2 - a syntactical bug corrected, thanks Brian de Alwis!
+
+
+PURPOSE
+
+This program can eliminate most private macros from a LaTeX file.
+Applications:
+ - your publisher has difficulty dealing with many private macros
+ - you cooperate with colleagues who do not understand your macros
+ - preprocessing before a system like latex2html, which is somewhat
+ unpredictable with private macros.
+
+PLATFORM
+
+This is a Python program, which I only have tried to run under Unix. But
+the Unix dependence is minimal (for example all the directory path
+references are platform-independent). It should be easy to adapt the
+program to Windows, and also to avoid command-line arguments.
+
+In case your Python is not in /usr/bin, you should change the
+top line (the "shebang" line) of the program accordingly.
+This top line uses the -O option for python (stands for "optimize").
+Without it, the program may run too slowly. If you do not care for speed,
+a number of other complications (the database, the checking for newer
+versions) could be eliminated.
+
+USAGE
+
+Warning: this documentation contains "less" and "greater" signs.
+Important information is lost when it is displayed as html.
+Click directly on the README file instead!
+
+Command line:
+
+de-macro [--defs <defs-db>] <tex-file-1>[.tex] [<tex-file-2>[.tex] ...]
+
+Simplest example: de-macro testament
+
+(As you see, the <> is used only in the notation of this documentation,
+you do should not type it.)
+
+If <tex-file-i> contains a command \usepackage{<defs-file>-private}
+then the file <defs-file>-private.sty will be read, and its macros will be
+replaced in <tex-file-i> with their definitions.
+The result is in <tex-file-i>-clean.tex.
+
+Only newcommand, renewcommand, newenvironment, and renewenvironment are
+understood (it does not matter, whether you write new or renew).
+These can be nested but do not be too clever, since I do not
+guarantee the same expansion order as in TeX.
+
+FILES
+
+<tex-file-1>.db
+<tex-file>-clean.tex
+<defs-file>-private.sty
+
+For speed, a macro database file called <defs-file>.db is created.
+If such a file exists already then it is used.
+If <defs-file>-private.sty is older than <tex-file-1>.db then it will not
+be used.
+
+It is possible to specify another database filename via --defs <defs-db>.
+Then <defs-db>.db will be used.
+
+(Warning: with some Python versions and/or Unix platforms, the database
+file name conventions may be different from what is said here.)
+
+For each <tex-file-i>, a file <tex-file-i>-clean.tex will be produced.
+If <tex-file-i>-clean.tex is newer than <tex-file-i>.tex then it stays.
+
+INPUT COMMAND
+
+If a tex file contains a command \input{<tex-file-j>} or \input <tex-file-j>
+then <tex-file-j>.tex is processed recursively, and <tex-file-j>-clean.tex
+will be inserted into the final output.
+For speed, if <tex-file-j>-clean.tex is newer than <tex-file-j>.tex
+then <tex-file-j>.tex will not be reprocessed.
+
+The dependency checking is not sophisticated, so if you rewrite some macros
+then remove all *-clean.tex files!
